i need some tool that can report access statistics to some command from my application.

In my case, commands are served by a java servlet that dispatches commads to the specialized controllers behind.

Servlets are just like CGI, they construct html pages dynamically.
URLs received look like http://www.myserver.com/MyApp/MyServlet.

MyServlet is the dispatcher (a unique entry point).
It determines the destination of the query based on an input form, let it be <input name="idCommand"/>

My questions are :
- is there any one who uses AWStats for this purpose ?
- Does anyone know about a tool that permits this statistics ?
- can anyone tell how to capture the <input name="idCommand" value="somevalue"/> from the http (idealy with apache logger) ?
